B16A Engine Light

Alright, so im kind of new to this site so take it easy. I have recently bought a 1992 JDM Honda Del Sol and its a beauty, but i'm starting to run into some minor troubles. For one, my engine light continues to turn on after i hit vtec. I was told it was my O2 sensor which i replaced and still face the same problems. I am also starting to hear a squeak coming from the engine around 2-3000 rpm's but it stops when i engage the clutch. I'm not mechanic but im guessing its a belt of some sort. If You can hit me with some adivce it would be greatly appreciated. Thanks.

Have you tried actually figuring out what the error code is? Just telling us that the CEL is on isn't going to get you anywhere. Take the car to AutoZone and have them plug in their diagnostic tool and tell you what the light actually means, then we can help you...
